To all whom it may concern:

Be it known that I, ROBERT JOHNSTON, a citizen of the United States, residing at the lcity of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Piano Card-Punching Machines, of whichf` the following is a specification.

My invention has relation to a piano cardpunching machine for punching jacquardcards for the manufacture of Wilton or Brussels rugs and'fcarpets; land in such connection it relates more particularly to the arrangement of punches and locking-keys in the head thereof to adapt the same to punch a card and its complemental card, in which will be repeated a'reverse of the design of the first card instead of punching the complemental card only and to reverse the design of the same during the punching thereof, as has been shown and described in Letters Patl ent No. 7 64,129, granted to me under date of July 5, 1904, for a machine for repeating pattern-cards.

The principal objects of my invention are, first, to so arrange the punches and keys vof the head of a piano card-punching machine as to punch the card as well as the complemental card in one operation and to reverse the designof the first card in the complemental card by the rigid connection of certain of the keys'with each other g second, to provide for this purpose the head of a piano card-punching machine with two groups of punches and two groups of keys, which are normally unlocked from the punches; third, to so connect the keys of the groups of keys with each other that when certain keys of one group are operated to lock their respective punches to the head certain keys of the other group will be likewise automatically operated for the same purpose, and, fourth, to divide the groups of keys and punches into sets of four and to so connect thesesets with each other that the card punched by the sets of keys actuated by the operator will be repeated in a reverse design in the complemental card punched by the other sets of keys Ycontrolled by the positively-operated sets of keys. The nature and scope of my present 1nvention will be `more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a top or plan view of the head of a piano card-punching machine, illustrating two groups of punches and keys normally disconnected from each other andy two groups of bars dividing by their connection with the groups of keys the same, as well as punches,

into sets of four, which punch a card and a.

complemental card and reverse in the complemental card the design of the irst card, all embodying main features of my said invention. Fig. 2 is a front elevational view of the head of Fig. 1. Fig. 3 is a top or plan view of the head, illustrating the connection of ke s to produce a reverse design in the comp emental card when the same is placed with its back toward the jacquard-needles. Fig. 4 is a front elevational View of the head of Fig. 3. Fig. 5 is a vertical sectional view of the head shown in Fig. 4 and ofthe punchingtable arranged below the same; and Figs. 6 and 7 are plan views illustrating, respectively, cards punched with the arrangement of keys and punches shownA in Figs. 1 and 3.

Referring to the drawin s, a represents the head, which by means o rods b and b is raised and lowered in a piano card-punching machine. (Notgshown) In the present instance the head a is provided with two groups of punches c and c', each group consisting .of punches ranging from 1 to 8, inclusive. The group c of the punchesfisf designed to be actuated by an operator, for which purpose each of the keys d2 of the group of keys d is held in an inoperative position in the head a by a spring e, arranged on the contracted or locking portion d3 of the key and bearing a ainst the expanded iinger portion d* thereof and the head a. Each of the keys dz'is thus held out of engagement with their respective punches c, which will not punch holes in a card when the head a is depressed. The other group of keys d being rigidly connected with the group d by a groupof bars I f engaging the fin er portions d4 of the keys d2 are likewise heFd in an inoperative position by the springs e. Thus when certain of the keys of the group of keys d are operated certain of the keys of the group TOO of keys d are simultaneously actuated. If, therefore, the keys of the group d should be connected in regular sequence with the keys of the group of keys d two cards g and g will be punched at a time by the groups of punches c and c, one being the exact counterpart of the other. For the manufacture of Wilton and Brussels rugs or carpets, however, it is necessary to reverse the design in the complemental card g', for which purpose, as shown in Figs. 1 and 2, the key d2 of the punch No. 1 of the group of punches c by means of the bar f thereof is connected with the key d2, controlling punch No. 4 in the group of punches c In the same manner the .punch No. 2 of group c is connected with punch No. 3 of group c', the punch No. 8 of group c with punch No. 2 of group c, the punch No. 4 of group c with punch No. 1 of group c', the punch No. 5 of group c with punch No. 8 of group c', the punch No. 6 of .group c with punch No. -7 of group c, the punch No. 7 of group c with punch No. 6 of group c', and the punch No. 8 of group c with ythe punch No. 5 of group c. As will appear from the card g, punched by the group of punches c in Fig. 6, such arrangement and connection result in reversing upon the card g the design of the card g, for if the first punch of the group c is operated the punch No. 4 of the group c repeats at 4 in the card g. Again, if inthe group of punches c the punch No. 7 is operated the punch N o. 6 in the group c is operated, which will repeat at 6 in the card g', and soon through the various rows of respective cards.

In Figs. 3 and 4 a modified form of the invention is illustrated in which in turning vthe back .of ythe cards g and g to the needles of a jacquard mechanism (not shown) instead of the face thereof the repeated card g/ will still have the design in reverse. In this instance the keys d2 of the groups of keys d and d and :by the same the groups of punches yc and c are connected with each other in the following manner: The punch No. 1 of group c with punch No. 5 of group c', the punch No. 2 of group c with punch No. 6 of group c, the punch No. 8 of group c with punch No. 7 of group c', the punch No. 4 of group c with punch No. 8 of group c', the punch N o. 5 of group c with punch No. 1 of group c', the

punch No. 6 of group c with the punch No. 2'

of group c', the punch No, 7 of group c with punch No. 3 of group c', and the punch No. 8 of group c with the punch No. 4 of group c.

From the foregoing description it follows that the groups of punches c and c', as well as keys d and d are arranged in two sets of four punches and four keys and that in Fig. 1 the Jrst set of punches c and keys d are connected with the first set of punches c and keys d and the last set of punches c and keys d with the last set of punches c and keys d in such a manner that the key d2 of the first punch of the first set of the group of punches c controls the fourth key d2 of the first set of the group of punches c, while the fourth key of the first set of the group of keys d controls the first key of the first set of the group c', and the intermediate second and third key in each set of keys of the group d and d controls the third and second key, respectively, in each set of the group d of keys. In Fig. 3, however, the first set of punches of the group of punches c is connected with the last set of punches of the group of punches c and second set of the group c with the first set of the group of punches c. Thus the first key of the first set of the groups of keys d is connected with the fifth key of the second set of the group of keys, the second key of group d with the sixth key of group d', the third key of group d with the seventh key of group d', and the fourth key, being the last key of the first set of keys of the group of keys d, with the eighth or last key of the second set of keys of the group of keys d. The fifth, sixth, seventh, and eighth key of the second set of keys of the group of keys d aie connected with the first, second, third, and. fourth key of the first set of keys of the groups of keys d. As shown in Fig. 5, the cards g and g are placed in the punching table or bed h of themachine and are fed forward in the saine after the completion of each row of punches by means not shown.

Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine of the character described, ka head, two groups of punches and two groups of keys arranged in sets of four in said head and normally held out of engagement with each other, two groups of lbars rigidly connecting the first set of four keys of one group with the first 'set of keys of the other group and a second set of keys of the first group with a second set of keys of the secondy group and by the same with their respective sets of punches and said keys arranged so that the first key in a set is connected with the fourth key in the second set aiid the fourth key with the first key and intermediate keys, the second and third with the third and second key in the set.

2. In a machine of the character described, a head, two groups of punches and two groups of keys arranged in sets of four, in said head and normally held out of engagement with each other, two groups of bars arranged to connect, respectively, the first key of the first group of keys with the fourth key of the second group of keys, the second key with the third key, the third key with the second key, the fourth key with the first key,
